城市交通微观模拟系统的构建

System Building of Microscopic Simulation of Urban Traffic

交通系统模拟是一门在数字计算机上进行交通实验的先进技术。通过对交通系统的模拟研究,可以得到交通流状态变量随时间和空间变化的分布规律及其与交通控制变量间的关系,从而实现对现有系统的再现和对未来系统行为的预先把握。重点讨论了整个模拟系统的构建过程,并论述了采用模糊控制技术来模拟车辆个体的原理和实现。

The simulation of traffic is an advanced technology used in traffic experiment via digital computer. Through the research to simulation of traffic system, the rules about discrepant distribution of traffic flow variables in time and space are concluded, and the relationship among traffic control variables are attained with aim of eventually achieving recurrence of current traffic system and prediction of future traffic system. In this article, the process of simulation system building is mainly discussed, and the theory and the realization of fuzzy control technology to simulate car are also presented.
